Re: Box design for ext cab silverado

Im getting a Silverado soon and Ive been researching this as well. With the hump in the middle you will need to mount the amp behind the seats if you want to port it because the ports will be firing to the driver side where the amp would be.

Do a search for "silverado" in the Build Log section, and I think its ados that has a Silverado ext cab box build there. Comes out to around 2.1 cubes, IIRC.

Re: Box design for ext cab silverado

I have a design that will allow all your needs, but it is for 1 10".
Don't get me wrong, a 10" ported in this box is NUTS. It is designed for 1 DD2510 and allows for the amp to mount under the port on the passenger side floor. (under the seat).

It is ~1.35cuft and tunes to ~37hz (lower in cabin).
THIS BOX IS NOT EASY TO BUILD! There are some weird angles and you need to be good a wood working. It plays off the vehicles acoustics and sounds GREAT though.
